CAR-DOOR TRACK.

sPncIFIoATIoN rol-ming part of Lettere Patent No. 616,476, datedDecember 27, 1898.

I Application filed July 13, 1898- Serial No. 685,852. (No model.)

To @ZZ whom t may concern/.-

Beit known that I, JAMES G. LA'wLnR, a citizen of the United States,residing at the city of St. Charles, county of St. Charles, State ofMissouri, have invented a certain new and useful Improvement in Car-DoorTracks, of which the following is a lull, clear, and exact description,such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,forming part of this specification, in which- Figure l is a sideelevational view of a part of a car-door, illustrating my improvedcardoor track. Fig. 2 is a sectional view on line 2 2, Fig. l. Fig. 3 isa detailed view of a piece of track, and Fig. l is a cross-sectionalview of a slightly-modified form of track.

This invention relates to a new and useful improvement in car-doortracks, the object being to construct a track of the character describedwhich will be simple, cheap, and easily applied and one which when inposition not onlyacts as a supporting-rail for the door, but alsoaffords a guide for the wheel in the door-bracket and assists in guidingthe door in its sliding movement, in addition to which the upper edge ofthe door is prevented from moving outwardly when goods are piled againstit inside the car, and the entrance of rain, dust, cinders, dac., at thetop of the cardoor is prevented.

In cross-section the track is substantially L-shaped, provision beingmade for strengthening the same at the junction of the vertical andhorizontal members, the vertical member being provided with openin gsfor the passage of attaching devices for securing the track to the sidewall ot the car.

In the drawings, A indicates the vertical member, which is adapted to besecured to the side wall of the car through the medium of bolts, screws,or other suitable attaching devices which pass through openings a,formed in said vertical memberand into the side wall of the car.

B indicates the horizontal member, which extends from the lowerextremity of the vertical member, the juncture between said two membersbeing strengthened by a fillet of metal b. Y

C indicates a vertical projection rising from the horizontal member-Bnear its outer extremity, said projection forming the tread or supportfor the han ger-wheel,which is secured in a suitable hanger attached tothe upper edge of the door.

In the drawings, d indicates the hangerwheel, and D the hanger, bothofwhich are shown in dotted lines. The flanges of the hanger-wheelextend on each side of the projecting rib C and rest upon the bodyportion or horizontal member B, said rib thus acting as a guide-rail forthe wheel d. The member B projects some distance beyond the raisedportion or rib C to afford a bearing for the flange of the hanger-wheel,and depending from its outer extremity is a iiange E, which cooperateswith the upper edge of the door to assist in guiding said door in itsmovement and at the same time prevents lateral movement of the door. l

It will be noticed by referring to Figs. 2 and 4 that the track issecured above the door-opening in the side of the car, so that when thedoor is in a closed position it is held against inward movement by theside wall of the car, its upper edge being held against outward movementby the flange E. This flange E also protects the door-opening from theentrance of rain, cinders, rbc.

As shown in Fig. 2, the flange E projects beyond the outer face of thedoor, while in Fig. et the upper edge of the door is cut away slightlyto receive said flange, the latter construction obviating the necessityof recessin g or bending the bracket-hanger to receive the flange.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

The herein-described car-door track-rail, the same comprising verticalsecuring member A, and a horizontal track member B, eX- tendinglaterally from the lower extremity of said securing member, and at rightangles thereto, the junction of said two members being reinforced by allet of metal b, and

raised guide or supporting flange C, extend- In testimony whereof Ihereunto al'x my ing upwardly from horizontal member, and signature, inthe presence of two witnesses, Io near the outer edge thereof, adepending this 9th day of July, 1898. angeE, at the outer extremity ofthe hor- 5 Zontal member, said parts being formed in- JAS G' LAXVLER'tegral, and arranged parallel to each other i Vitnesses: throughout theentire length of the track; JOS. H. ALEXANDER, substantially asdescribed. l GUS. I-I. WILKE.
